Gold is a noble metal that, in comparison with silver and copper, has the advantage of corrosion resistance. Despite its high conductivity, chemical stability and biocompatibility, gold exhibits high plasticity, which limits its applications in some nanodevices. Here, we report an experimental and theoretical study on how to attain enhanced mechanical stability of gold nanotips. …

Carbon nanotubes can be chemically modified by attaching various functionalities to their surfaces, although harsh chemical treatments can lead to their break-up into graphene nanostructures. On the other hand, direct coupling between functionalities bound on individual nanotubes could lead to, as yet unexplored, spontaneous chemical reactions. Here we report an ambient mechano-chemical reaction between …

Brazilian Physical Society highlighted Nature Communications article about sponges: Low-density nanostructured foams are often limited in applications due to their low mechanical and thermal stabilities. Here we report an approach of building the structural units of three-dimensional (3D) foams using hybrid two-dimensional (2D) atomic layers made of stacked graphene oxide layers reinforced with conformal …

The ” Dynamical aspects of the unzipping of multiwalled boron nitride nanotubes” by Eric Perim, P.A.S. Autreto, Ricardo Paupitz and D.S. Galvão was chosen article in the cover letter of Physical Chemistry Chemical Physics in the edition number 15. Boron nitride nanoribbons (BNNRs) exhibit very interesting magnetic properties, which could be very useful in …

Rice highlighted Nature Communications article in its main homepage. Chandra Sekhar Tiwary, a graduate student at the Indian Institute of Science, Bangalore, with a complimentary appointment at Rice, is co-lead author of the paper. Co-authors include Pedro Alves da Silva Autreto, a researcher at the State University of Campinas, São Paulo, with a complimentary …
